You can view the AppleTalk routing tables in your network through the Administration Console.

AppleTalk Echo Protocol (AEP). AppleTalk nodes use the AEP to send datagrams to other nodes in the network. It causes the destination node to return, or echo, the datagram to the sending node. This protocol can determine whether a node is accessible before any sessions are started, and it can enable users to estimate the round-trip delay time between two nodes.
